TARA PLANT (BEIGE)
1. Caesalpinea spinoza, commonly known as tara, is a small leguminous tree or thorny
shrub native to Peru. T. spinosa is cultivated as a source of tannins based on a
galloylated quinic acid structure. T. spinosa is placed in the family Fabaceae,
subfamily Caesalpinioideae, and tribe Caesalpinieae.
2. T. spinosa pods are an excellent source of environmentally friendly tannins (tara
tannins) most commonly used in the manufacture of automotive and furniture
3. Tara tannin derivatives are being proposed as antifouling against marine organisms
that can grow on ship hulls. Those tannins are of the hydrolysable type. Gallic acid is
the main constituent of tara tannins (53%) and can be easily isolated by alkaline
hydrolysis of the plant extract.
4. Quinic acid is also a constituent of the tara tannins. Its tannines are colourless or
light making them a suitable premordant in the dyeing of cotton and other cellulose
5. Medicinal uses include gargling infusions of the pods for inflamed tonsils or washing
wounds; it is also used for fevers, colds, and stomach aches. Water from boiled,
dried pods is also used to kill fleas and other insects.
6. T. spinosa pod powder produces beautiful light to dark beige, brown shades on
cotton, wool, silk and all natural textile substrates by standardized dyeing process
using different combination of natural mordants on fibers, fabric and garments with
excellent fastness properties.
